If angles A and B are complementary they are both what type of angle?
acute
100
The sum of the measures of two supplementary angles is _______ degrees.
180
100
What is the measurement of angle C?
120 degrees

If you knew that two angles were complementary and were given the measure of one of those angles, would you be able to find the measure of the other angle? Explain your reasoning.
Yes, because one angle would be known and if two angles are complementary, then the measures of the two angles sum to 90 degrees.
200
An acute angle is less than _________ degrees.
90
200
If A and B are complementary and A measures 20 degrees what is the measure of B?
70 degrees
200
If A and B are supplementary angles and Angle A measures 21 degrees, Angle B is ____________ degrees.
159
200
TRUE or FALSE: Vertical angles are always Acute.
FALSE
200
Are angles a and b complementary, supplementary, or neither?
Complementary; 90 + a + b = 180, so a + b = 90
